A patient is receiving high-frequency chest wall oscillation treatment but is not mobilizing any secretions. The patient is in an inflatable vest, and the generator seems to be working properly. The frequency setting is at 3 Hz. The superimposed small positive pressure is 0.0125 psi.

What could be the cause of the vest not mobilizing secretions?
  1. The patient is not cooperating
  2. The IPV setting is not accurate
  3. The Hz setting at 3 is too low
  4. The patient does not respond to kinetic therapy
Explanation
Answer: C-A possible cause of the vest not mobilizing secretions is the setting being too low at 3 Hz.

A high frequency chest wall oscillation device should be set with the air-pulse generator at controlled frequencies between 5 and 25 Hz.
